In this article we argue that “smart” work spaces are created through access to wireless networks and mobile cloud computing collaboration software. Yet the power relations embedded in these overlapping physical and cyberspaces function to control the spatial and temporal fragmentation of related work activities. Through a review of the literature, we first describe how scholars have considered the relationship between space, technology, and the workplace and how conceptions of work activity fragmentation developed over time in relation to computing technology. We provide data from the American Time Use Survey to show the extent of work activity fragmentation among workers in the United States, finding that spatial fragmentation is more prominent among knowledge workers in large metropolitan areas. Drawing on original interview and observation data in the New York metropolitan area, we then describe both the cyberspaces of work enabled by mobile cloud collaboration software and the physical spaces of work opened up by the availability of wireless networks in diverse locations. Finally, we consider how the exercise of power and control in these overlapping physical and cyberspaces can either enable or prevent the fragmentation of work activities at multiple points. Key Words: activity fragmentation, cyberspace, information and communication technology, power relations, smart space.

在本文中，我们认为，“智能”工作空间是通过访问无线网络和移动云计算协作软件而创建的。然而，嵌入在这些重叠的物理和网络空间中的权力关系起着控制相关工作活动的时空分割的作用。通过回顾文献，我们首先描述了学者如何考虑空间，技术和工作场所之间的关系，以及随着时间的流逝，与计算机技术有关的工作活动碎片化的概念是如何发展的。我们提供的《美国时间使用状况调查》中的数据显示了美国工人中工作活动的分散程度，发现在大都市地区的知识型工人中，空间分散更为突出。利用纽约都会区的原始采访和观察数据，我们将描述由移动云协作软件支持的工作网络空间和因在不同位置提供无线网络而开放的物理工作空间。最后，我们考虑在这些重叠的物理和网络空间中行使权力和控制权如何能够启用或防止工作活动在多个地点分散化。关键词：活动分散，网络空间，信息和通信技术，权力关系，智能空间。
